Blender production Challenges – Call for content (yes still a few months to go :)

Hello Blenderheads,
I’m Olivier, and I presented the Open-Stage blender Production Challenges at last year’s blender conf.
I would like to get your help for this year.
You can see my blogpost about last year here . And also the video here

Possible Improvements for this year:
Some things that will need to be improved :
– The internet connection at the conf venue (not my fault 🙂
– A way to distribute the challenge files faster.
– A better way to interact and discuss with online people (have someone in the room to check IRC and help participate)
– Have more people sending in the challenge files before the conference.

Call for challenge files
So, this post is all about the last point: I would like to get more files from you, blender users.
Usually these challenge files come out from a problem that you had (or still have) during a production or image creation. They have a broad range: Something that weirdly behaves not the way you want or expect (no bug wanted here, it could be just a rig that maybe doesnt bend correctly even with rotation locking, or maybe something that you are stuck with, like how to change the color of an instanced group randomly. Other examples: you try to render an image, but an object doesn’t render correctly.
I will not be able to show all files during the conference, and will have to do a selection of the most interesting ones. The ones that could start a debate or technique sharing. But possibly all will be shared somewhere online after the conf.

what to provide
The best format is a simple lightweight blender file, which focuses only on the problem. We do not want too many useless artefacts around. A bit like when you send a bugreport file, you squeeze it down to only the part that you are interestred in. For example if your challenge is about rigging, you do not need a complicated animated sculpted textured character.
Ideally you should provide a text file (inside blend file or outside as .txt ) with the explanation of the problem (and your solution :p). You can append images if needed. And try to rate its difficulty level ( we need hard ones, as well as easy ones) I might re-edit them a bit + beware that they will be redistributed, so be sure to provide only content that is not afraid to be copied around the world wild web.
If possible size should be reasonable.

Feel free to look at the files from last year and provide better ones 🙂

Thank you and looking forward to get your feedback and maybe files. You can send me a link to files oenvoyage AT or by writing a comment here. I’m also on twitter @oenvoyage and sometimes on IRC


Blender conference + challenges files

In this post I will share the files I used for my presentation called blender challenges.
But first I have to apologize for posting a short blogpost, my wife is here and we are going to visit Amsterdam for 2 days, so not much time for writting 🙂

This was one of my best conference, if not simply the best! Got the chance to meet a lot of new people, especially some swiss guys this time too! 🙂 Hope we can do some gathering one day soon.

Apart from meeting people (which takes some time and even makes you miss some talks because chatting and sharing is so much fun) you also get the chance to see talks and presentation of techinques, researches or simply showcases of what people do with blender.

Blender Challenges
I had the chance and task to host the open-stage time slot, and so decided to share some files and problems encountered during some productions, but in a simplified way. It resulted in a series of 6-7 .blend files, with something wrong in them, and people would need to solve them.
The files were handed out at start of the talk, and folks had to gather in groups and try to solve them. The few first ones were rather easy, ranging from bad oriented normals, to overlaping faces. some others were a bit more tricky. The audience was very participative and it started some nice discussion and trick sharing, I loved it.
Instead of giving out the answers, I will give out the files for your pleasure and you can try to solve them.
Here is the link: (1.1 mb)
I hope you can enjoy them as much as the audience did 🙂
Can you solve them ? Do you have some answers ?
Do not read the comments if you dont want to be spoiled 🙂
